The flathead sole is a right-eyed flounder with an oval-shaped body. Its upper surface is dark in colour, olive brown to reddish grey-brown, and may have dusky blotches; its underside is white with translucent areas. The dorsal and anal fins also have dusky blotches. The upper jaw is narrow in the middle and has one row of teeth. The U.S. lands the majority of the world's catch of flathead sole and manages three fisheries - one in the Bering Sea and Aleutian Islands, one in the Gulf of Alaska and one off the West Coast. Commercial fishing is conducted by trawler. Annual catches average around 17,000 tons in the Bering Sea and Aleutian Islands area; in 2008 the Gulf of Alaska catch reached its highest ever level of 3,396 tons.
